中文摘要：
在二维凝胶圆盘体系中，研究过渡金属离子对草酸钙晶体生长和周期性环状沉淀的影响，并对其形成机理进行探讨。结果表明：在一定浓度的Fe^3＋存在下，体系中出现了周期性环状沉淀现象。同时发现在此条件下抑制了一水合草酸钙（COM）晶型生成。此外，加入Zn^2＋、Co^2＋、Ni^2＋体系中的晶体都以二水合草酸钙（COD）为主；而加Cu^2＋离子的圆盘中，三水合草酸钙（COT）占据了主要的成分，这说明不同的过渡金属离子对三种草酸钙晶型的生成影响不同。另外，还对出现的与尿结石有关的特殊现象（白斑和放射状的条纹）进行了探讨。
英文摘要：
Influences of transition metal ions on crystallization of calcium oxalate and the formation of periodic ring precipitation were investigated in the two - dimensional agar gel system. The results indicate that periodic ring precipitation produced with a certain concentration of Fe^3＋ , and the formation of COM was inhibited . In addition , the main crystal form is COD in the gel with Zn^2＋ , Co^2＋ , Ni^2＋ , while COT in the gel with Cu^2＋. These results show that different metal ions had different influence on the crystallization of CaC2O4. Furthermore , the special phenomena in agar gel which was similar to the blaze and the radial stripes in urinary stone were discussed.
